st: xtlogit multilevel modelling question

I am a new user of stata and am trying to use the xtlogit command for
multilevel modelling of a binary dependant variable. Is it possible
to include level 2 characterisitcs in the model (in my case level 2 is
the neighbourhood and it is neighbourhood characteristics I wish to
include also), and is there a facility for including interactions
between levels 1 and 2?
